Kns valmet adj. gas piston for jra gallant - KNS Precision Adjustable Gas Piston System

Installation was super easy. 1/8” roll pin punch and small hammer is all that was needed. Before installing the rifle was way over gassed. The brass was ejecting over 15 feet, recoil was excessive for the caliber and the carrier was bottoming out. It was beating the rifle to death. After installing, brass now ejects 8-10’, recoil is a pussycat and no more bottoming out. Adjustment sweet spot was 13 clicks from full closed. Tried rifle with Lake City, GGG, ZSR, steel cased import, everything fed and ejected with ease. Just a great improvement all the way around. As an added bonus, OP has the best price!
